Description

A sludge storage bin for sludge storage and transportation

technical field

The utility model relates to the field of solid waste treatment and environmental protection, in particular to a sludge storage bin used for sludge storage and transportation.

Background technique

Sludge is a kind of muddy substance produced by the metabolism of pollutants and microorganisms in the process of sewage treatment. The sludge treated by the dehydrator still has a water content of 80% and a density of about 1.1g/cm ³ . The solid matter in the sludge is divided into inorganic matter and organic matter. Inorganic substances: mainly inorganic minerals, as well as various forms of heavy metals and nutrient salts. Organic matter: microbial residues, biofilm, cellulosic matter. Undisturbed sludge is generally jelly-like and mushy, which cannot be accumulated and will drip when transported. When fully dehydrated, it can become dry lumps, slag, and sometimes can block pipes and pores. In the process of dehydration, handling, etc., bricks, stones, and branches will be mixed in. Due to this state of the sludge, during the storage and transportation of the sludge, the sludge often has phenomena such as uneven feeding or even arching, which affects the controllability and continuity of the sludge transportation.

At present, domestic urban sewage needs a large number of supporting equipment for sludge treatment and disposal. The equipment for receiving, storing and conveying sludge is a particularly important part of it, which involves the measurement and transportation of sludge. The existing sludge storage and conveying systems are divided into two categories, one is using plunger pumping, which requires large investment and high energy consumption; the other is using a simple screw conveyor, which has problems such as difficult to control the conveying volume and prone to blockage .
